' In the packeting of cigarettes or like goods afdefinite number-of cigarettes are combined toform agroup and delivered to the box or packet. In, general several groups are.

" placed in "superposed layers in the. box or 7 packet and it is necessary therefore to lay the collected, groups in superposed layers. This can be effected by suitably delivering them to the packet or box but it is not possible'with packets or boxes in'which the cigarettes must be inserted from one end. In. such cases the groups of cigarettes must be first placed one over the other and the whole of the intended ;contents pushed into the packet or box by V umeans of a plunger or. the like. i a o o a The; present invention provides a solution of the problem of collecting the separate cig ,arettes. into groups of suitable number and .7ofgplacing,thesegroups in the desirednumher of layers so that they can be pushed as a'whole into the packet or box.

: Many suggestions have alreadvbeen madefor thls purpose The present invention affords-a new solution in. which the cigarettes '7 fed forwards alone a feed band to an abutmentor stop after the necessary number to form a groupchave been collected are raised bv 7 means of'an elevating device into the path of a plunger or pusher so that by arranging ad-1 jacent one another number of collecting devices and superposing several parallel. pushf or tracks a suitable number of layers of groups located one above the other may be 7 combined.

Preferably the feed track consists of two parallel bands or belts between wh ch the elevating device moves and over which the cigarettes project laterally with their ends,.

an upper covering being provided each cigarette end adjacent the collecting. station each of which is formed as an operating lever which during the elevation of the cigarettes is moved by suitably controlled rods so that the ends of the cover leave the cigarettes free to the operating lever. The invention is illustrated in the accompanying drawings in which Fig. 1 is a side velevation and Fig. 2a front elevationpartly .50 in vertical section on the line 22 of Fig; 1.

. The embodiment illustrated deals with the,

packeting of cigarettesof oval cross section. The separate cigarettes are continuously deposited by kIlOWnmeans'on the upper flight of two parallel feed bands 1 which are ledover the guide pulleys 2 and 3. i The guide pulleys 3 onthe spindle 4: are driven by a,

train of gearing 5, 6from 't-heinain shaft 7.

The upper flights ofthe feed bands 1 are I it moved in the direction of. the arrow indicated in Fig. l and near theiend of thefeed track is provided a fixed'inclined stop or surface 8 arettes projectlaterallybeyond the flights of i a the feed bands 1. l-koljacentthe collecting station the cigarettesare covered by covering surfaces 9 which in known manner prevent the piling and'rising of the cigarettes. i These surfaces form the free ends of hell crank levers 10 whichvarelpivotally mounted about the pivots 11 on'the frame A. With the bell crank levers are connected rods 12which with their forked ends embrace the shaft 7 and are v guided thereby. Moreover the rods provide horizontal pivots 13 on which are freely rotatable rollers, 14 which t k Cam discs 15 mounted on (the haft; 7." The recesses 16. in

these camdiscs permit a downward movement of the rods 12 under the action of the I springs 17 secured thereto. The bell :crank leversl O are thereby rocked and the covering surfaces 9 moved out of the zpathof the cig arette ends sot-hat the cigarettesmay be el'e vated.

This elevating movement is eifected by an elevating device 18 which consists of an angle member (see Fig 1) carried by two links 19-, 20' which'are pivoted at21, 22 onthe bracket: B and at.23, 24 are pivotally conf I nected to, the elevatin device 18.

On the shaft 7 is mounted a cam-disc 25 i the cam 26 of which raises thjexelevating demountedjon the lower link 20. These. links vice by engaging the roller 27 ,which is ensure that in the elevating movement the uper an ular surface 18 of the elevatinm device 18 remains horizontal sothat the group of cigarettes resting on this surface can be raised without being disturbed or sliding off.

The cigarettes are raised to the level of a feed track C. After they are raised a plunger or pusher 28 which moves in the direction indicated by the arrow in Fig. 2 moves forward and takes with it the group of'cigarcttes in the feed channel C.

Several feed bands 1 are arranged adja-' cent one another and a number of tracks C, C etc. one above the other. Accordingly the adjacent elevating device 18 which is indicated at the left hand ofFig. 2. in dotted lines can elevate the group of cigarettes fed thereby to the level of the feed track C so that this group on the further feeding movement to the right is located above the lateral group in the feed track C and the two groups can be'fed as superposed layers in known manner into the packet or box held ready for the purpose;

On the elevatingmovement the downwardly extending angular face of the elevating device 18 forms a stop for the cigarettes ar-' riving onthe feed bands'l, so that first of 'all a number of cigarettes may be allowed to collect which is considerably greater than the number intended to form a group. lVh'eu the elevating device moves upwards it separates the group and forms an abutment surface for the, further forward movement of the already collected cigarettes. Thus in all cases sufficient cigarettes are provided for the formation of the next group.

.The operating means forthe elevating device may beso arranged that in the upward movement it moves in the direction of the longitudinal axis of the cigarettes. Accordincluding an inclined stop at ingly these cigarettes in such elevating in ovement remain in their position of rest and the whole group is pushed upwards in the i11 clined directionof the said longitudinal axis without' the separate cigarettes moving from their position. Such an elevating movement can easily be obtained by correspondingadjustment of the links 19, 20 withrespect to one another and by a corresponding arrangement of the pivots 21, 24.
